Abstract: PURPOSE:To make flow velocity uniform in width direction at outlet of the last slit of molten steel and to improve the quality of a cast slab by forming plural steps of manifolds having width size larger than the slit width at plural positions in vertical direction of the slit formed at inner part of a core. CONSTITUTION:The molten steel 7 flowing down from a flow-down hole 10 in a tundish 6, is poured into the slit 14 while eliminating difference of the flow velocities in the width direction by stagnating of flow with the passing-through resistance of the slit 14 communicating with lower part of the upper manifold 15 and widened in the width direction and caused to flow down. Successively, the molten steel 7 is caused to flow into the slit 14 while further averaging the flow velocity in the width direction again at the lower manifold 16, and the flow velocity in the width direction is made to almost uniform at the outlet of the slit 14, and the molten steel is poured into molten steel basin 3. By making the pouring velocity uniform in the width direction as the above, the max. velocity of the molten steel 7 is decreased and the range of dead zone, where the pouring of the molten steel into the molten steel basin 3 is not entirely executed, is reduced, and as the uniform pouring in the width direction is executed, uneven thickness in the width direction of the cast slab 9 and further, the development of bulging can be prevented.

Filed: 1989-04-03
Abstract: PURPOSE:To make it possible to measure the water level of a boiler drum highly accurately by measuring the temperature in a condense pot, and correcting the specific gravity of the water in the condense pot based on the temperature. CONSTITUTION:A temperature measuring resistor 13 is attached to a condense pot 2. The measured temperature is transduced into an electric signal through a temperature transducer 14. The electric signal is supplied to a first correcting part 16 through a third input part 15.

In a subtracting part 18, the difference (gammas-gammaa) between the specific gravity of saturated steam and the specific gravity of the water in the condense pot is computed. A water level h' of the drum is computed based on the value, the difference (gammaw-gammas) between the saturated water and the specific gravity of the saturated steam and a differential pressure signal DELTAP of the condense spot 2. Therefore, the water level of the drum can be computed more accurately than with a conventional apparatus.

Title: Exhaust valve for hemomanometer
Inventor: BURAJIUSU SHIYUPAIDERU
IPC: F16K7/06
Filed: 1985-04-18
Abstract: An air release valve for sphygmomanometers in the form of a flow metering device in an air outlet duct comprising a length of a flexible tube as part of said duct and a pressure member which is displaceable against the valve tube by means of a pivot lever, so as to collapse one tube wall against the other to close the cavity of the valve tube and to produce an initially very gradual and later progressively greater opening response, when the pressure member is retracted and the valve tube is allowed to return to its open state. The valve tube may be an arcuate tube portion extending freely between two parallel spouts of the air outlet duct, or it may be a straight tube portion confined in a longitudinal groove of the valve housing. A U-shaped leaf spring between the valve housing and the pivot lever provides a valve closing force, finger pressure against the pivot lever produces a controlled valve opening action.

And these two types of pulse duration signals are transmitted to actuator 3 installed at the site in the form of the optical signals and via optical fiber transmission line 2. At actuator 3, the red and green optical signals transmitted from gauge 1 are selected through filters 31 and 32 each to be received at photodiodes 41 and 42. The current corresponding to the pulse duration of the received light flows at diodes 41 and 42 each. Thus output signal (er) of the parallel diode circuit, i.e. the current flowing to force motor 51 becomes to the current which corresponds to the difference of the pulse duration of the two pulse duration signals.

Title: Manufacture of semiconductor device
IPC: H01L27/092
Filed: 1992-04-03
Abstract: PURPOSE:To restrain the generation of a crystal defect by forming a continuous amorphous layer from an Si substrate surface to an inside thereof by implanting Si to the Si substrate surface and by performing a thermal treatment after impurities are implanted to the Si substrate surface at high energy. CONSTITUTION:After P<+> is implanted onto an Si substrate 1 at high acceleration energy, Si<+> is implanted. In the process, an amorphous layer 2 whose upper side coincides with a surface of the Si substrate 1 is formed. Then, crystallinity is recovered solid-phase epitaxially by annealing. In the process, since an original amorphous/crystal interface 1a exists in a lower side of the amorphous layer 2 alone, crystallization begins from the lower side alone. Thereby, the generation of crystal defect caused by wrong matching in a junction interface can be restrained.

Abstract: PURPOSE:To maintain high critical current density, and to improve various kinds of characteristics of a superconducting coil by a method wherein the forming position of an oxide superconducting layer is made to eccentric toward the inside of the radial direction of the winding body within the cross section in radial direction of a superconducting wire material. CONSTITUTION:A superconducting oxide layer 3 is buried in a silver tape-like substrate 2 along the longitudinal direction on a super-conducting wire material 1, said superconducting layer 3 is formed eccentrically from the center of the rectangular cross section of the substrate 2. A superconducting coil is constituted by winding the eccentric superconducting layer 3 around a winding jig 4 in such a manner that the layer 3 is positioned inside the jig.
